RAILROAD TRACKAGE Filed Jari. 27, 1938 lNVENTOR l I FEEDER/C J CHEM/DL/NBY W Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a system of track construction for railroads,more particularly for use with scale model railroads. Heretofore thestandard T-rail has been secured to cross ties with spikes or screwbolts. When small scale model railroads are constructed'these spikes andscrews become so small that they are diillcult to handle and areinadequate to properly secure the track to the cross ties.

The object of my invention is to produce a new rail section and crosstie that will overcome all the above disadvantages and give asatisfactory railroad track that is inexpensively and convenientlyconstructed.

The foregoing and other features of my invention will now be describedin connection with the accompanying drawing forming a part of thisspecification in which I have represented my rail system in a preferredform after which I shall point out in the claim those features whichIbelieve to be new and of my own invention.

In the drawing:

Figure I is a section of my rail.

Figure 11 is an isometric view of my cross tie.

Figure III is an enlarged detail showing how the rail is secured in theslot in the cross tie.

Figure IV is an isometric view of my track assembly.

In the carrying out of my invention I employ a T rail III the upperportion having substantially the proportional dimensions of the standardrail now in use in all railroads. Depending from the base II andintegral with the rail is a web I2 approximately the same thickness ofthe web I3 of the T rail I0. I2, I provide an enlarged portion It.

In Figure I, I show this enlarged portion, shaped with barbs I5 oneither side of the web I2.

Cooperating with my rail III I employ a plurality of cross ties 20.These ties are provided with two slots 2| having the same width as theOn the lower edge of this web thickness of the web I2 and a depthsubstantially the length of the web extension below the base I I.

In Figure III, I show my rail III press fitted into a slot 2|, thefibers of the tie being deflected to permit entry of the enlarged end of5 the rail l4 and when the rail is in its final position the fibersrebound above the barbs I5 to hold the rail firmly in the slot.

In Figure IV, I show an assembly of my track system. The rails III arespaced to a predeter- 10 mined gauge; the base II of the rail rests uponthe upper face of the cross ties 20; the web I2 ils in slot 2| and heldtightly in place by thebarbs While I have shown the enlarged outer edgeI4 15 of the web I2 in the form of ablunt arrow head,

I do not wish to limit myself to that specific construction as anyenlarged end would serve the purpose.

I wish it distinctly understood that my rail 20 track system is in theform I desire to construct it and that changes or variations may be madeas convenient or desirable without departing from the salient featuresof my invention and I therefore intend the following claim to cover such25 modifications as naturally fall within the lines of invention.

I claim:

In a small scale model railroad system, a track comprising a pluralityof cross ties provided with 30 slots cut transverse the length thereof,a rail having a web projecting downwardly from the base of the rail andadapted to be forced vertically into the slots in the cross ties, saidweb having an enlarged end extending the entire length of the web,whereby the fiber of the tie having been longitudinally compressedtemporarily while the rail is being inserted in the slot will return tonormal, thereby gripping the rail and preventing its removal.
